Ibis 93: 468
The history of the status of the Nile Valley Sunbird Nectariniu nietallica in Lower Egypt has been described by Greaves and Tregenza and by Greaves. The species is now a regular winter resident at Cairo where formerly it was only a straggler. Although this sunbird is found in South-west Arabia, in Egypt no previous record has been published of occurrences other than in the Nile Valley. Its northerly movements in winter and dependence on the flowering of certain plants are interesting points in the biology of this bird.
